Using the keyboard to visualize the relation between notes and accidentals is a great way of doing so because of the keyboards wide range.

Another way to locate keys and accidentals is through semi-tones and whole tones.
For example:
- A semi-tone ABOVE D would be D#, but also Eb. That’s because D# and Eb share the same key but are differently labelled for various other reasons. A semi-tone BELOW E would be Eb.
- Whole tones go up by a whole, so a whole note above A would be B and a whole note above G# would be A#.
- However, the notes that don’t have accidentals between them would just go straight to the key beside it.
- A semi-tone above E would be E# AND F, but a whole tone above E would be F#.
